3. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#3 Custom TeleComm™ Panel Overview

4. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#4 The Custom TeleComm™ Solution  Standalone real-time monitoring and control of systems  Low cost  Open access  Dedicated phone line  Varies from standard VeriComm ® panels

5. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#5 Operator Equipment Requirements  Computer with modem and VT100 terminal software  Laptop recommended for local access  Null modem cable for local connection  Numeric pager for receiving alarm notifications  Microsoft Excel recommended  Optional wireless Bluetooth ® kit available

6. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#6 Typical Custom TeleComm™ Panel  Most panels include …  ATRTU controller  24VDC power supply or 36VAC transformer  Output relays  Contactors, circuit breakers, HOA switches  Audible and visual alarms

7. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#7 Custom TeleComm™ Panel Sensor Options  In-panel sensor options  Current sensors  Temperature sensor  External sensor options  Flow  Liquid level  Pressure sensors

8. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#8 Custom TeleComm™ Panel Operation  Panel continually monitors activity and controls devices based on programmed panel logic  Pumps are controlled by ATRTU when HOA switches are in the “auto” position  Parameters, such as timer values, are changed via local or remote computer connection  Data is continually stored for retrieval via local or remote computer connection

9. TeleComm™ Control PanelsTPP-TCOMM-17/29/05#9 Custom TeleComm™ Alarm Reporting  Alarms are reported immediately via numeric pager  Prolonged alarm conditions repeatedly page at regular intervals  Local alarms are delayed to give operator time to respond remotely  Operator connects to the panel locally or remotely using terminal software to evaluate and possibly correct the alarm condition
